I take we are talking about fractional distillation.
a. In terms of the separation a small amount of a soluble nonvolatile impurity will have no effect. There will be a small increase in each of the boiling points, which are already well separated.
b. A decrease in the barometric pressure will bring the boiling points closer together and thus more theoretical plates are needed to achieve separation. Or, if you like with the same apparatus, a poorer separation.
c. An increase in barometric pressure will increase the separation of the boiling points, so less theoretical plates needed. Or, if you like with the same apparatus, a better separation.
d. Not quite sure what is meant by this. Is the implication that the vapour is not at equilibrium?
